The ADC128S102CIMTX/NOPB from Texas Instruments is a 12-bit successive-approximation analog-to-digital converter with eight multiplexed analog inputs, housed in a 16-pin TSSOP. It converts at up to 1 Msps through an SPI-compatible serial interface and runs from a 2.7 V to 5.25 V supply, with 5 V nominal operation. A SAR converter of this class samples one channel at a time through an input multiplexer, so the 1 Msps throughput is shared across the eight inputs rather than provided per channel. Integral nonlinearity is specified at 1.2 LSB and signal-to-noise ratio at 73 dB, with power consumption of 2.3 mW.

Eight-channel SAR converters are used wherever a controller must digitise a group of slow-moving analog rails and sensors from one device: power-supply and system monitoring, motor and drive control feedback, portable instrumentation, and multi-sensor industrial data acquisition. The shared multiplexer suits scanning applications rather than simultaneous sampling, so designs needing phase-coherent capture across channels use a different architecture. Typical buyers are industrial automation, test and measurement, and embedded-systems OEMs. The device is in Production status with an Active manufacturer lifecycle, is RoHS compliant and lead free, and ships on tape and reel in 2, 500-piece quantities.
